[tlbuild] tl-update-containers only creates an empty package

[Henri Menke]

Dear list,

This probably comes at an inconvenient time, amidst all the TeX Live 2019
stress, but I have a question.

I want to build a custom TeX Live repo for PGF/TikZ which can be used similar
to tlcontib.  To this end I reformat the directory into TeX Live tree structure
and run tl-update-tlpdb and tl-update-containers on it.  Unfortunately, this
only creates and empty pgf.tar.xz package for me (only tlpkg/tlpobj/pgf.tlpobj
is inside) and the resulting texlive.tlpkg says

    [...]
    name pgf
    category Package
    revision 0
    relocated 1
    [...]

The steps to reproduce are:

    $ git clone https://github.com/pgf-tikz/pgf
    $ bash build.sh

The contents of build.sh can be found below.  What am I doing wrong?

Cheers, Henri
